ERRATA, ERRATUM
Reading edition
Do not be guilty of the absurd mistake of printing ‘Errata’ as a heading for a single correction. When a list of errors has been dealt with, by printing cancel pages and otherwise, so that only one error remains, take care to alter the heading from ‘Errata’ to ‘Erratum’. The same remarks apply to Addenda and Addendum, Corrigenda and Corrigendum.
